Description
In the present research, we suggested non-linear heating regime for the thermogravimetric (TG) determination of kinetic parameters of solid-state reactions. The method is based on the application of a hyperbolic heating mode. The method allows the reaction activation energy and kinetic function to be obtained from a series of non-isothermal experiments. Kinetics of the model solid-state reaction Fe2O3+Li2CO3=2LiFeO2+CO2 was investigated by the suggested method. The kinetic parameters obtained are in a good agreement with the reference data.
